#1
Front (Question)

What is the general formula for an alkene?

Back (Answer)

CnH2n+2

#2
Front (Question)

Do alkenes have double bonds?

Back (Answer)

Yes

#3
Front (Question)

How do you name an alkene?

Back (Answer)

-ene

#4
Front (Question)

What types of isomer can alkenes form?

Back (Answer)

Chain, position, geometric/stereoisomerism

#5
Front (Question)

How do you decide if it is an E or Z isomer?

Back (Answer)

Z = chains with greatest atomic mass on same side. E = chains with greatest atomic mass on opposite side

#6
Front (Question)

Are alkenes soluble in water?

Back (Answer)

No

#7
Front (Question)

Boiling point trend as carbon chain increases?

Back (Answer)

Boiling point increases as carbon chain length increases because there are increased VdW forces.

#8
Front (Question)

What reactions can alkenes undergo?

Back (Answer)

Combustion, electrophilic addition

#9
Front (Question)

What is the combustion of alkenes reaction?

Back (Answer)

Alkene + oxygen –> carbon dioxide + water

#10
Front (Question)

What is an electrophile?

Back (Answer)

An electron pair acceptor, attracted to areas of electron density

#11
Front (Question)

Describe the mechanism for electrophilic addition of alkenes

Back (Answer)

Electrophile attracted to the double bond. The electrophile accepts a pair of electrons from the double bond. A carbocation is formed. A negatively charged ion forms a bond with the carbocation.
